Nanoplasmonic renormalization and enhancement of Coulomb interactions

In this paper, we propose a general and powerful theory of the plasmonic enhancement of the many-body phenomena resulting in a closed expression for the surface plasmon-dressed Coulomb interaction. We illustrate this theory by computing the dressed interaction explicitly for an important example of metal–dielectric nanoshells which exhibits a rich resonant behavior in magnitude and phase. This interaction is used to describe the nanoplasmonicenhanced Förster resonant energy transfer (FRET) between nanocrystal quantum dots near a nanoshell. 3 On sabbatical leave as an Invited Professor at l’Institut d’Alembert, Ecole Normale Supŕieure de Cachan, 94235-Cachan, France. 4 Author to whom any correspondence should be addressed.
